(54)	System and method of controlling an electronic price label

(57) A system and method of controlling an electronic price label (EPL) through infra-red signals instead of push-button signals. The system includes a computer which transmits wireless radio frequency messages containing functions codes and instructions, and a portable terminal which emits infra-red signals containing at least one of the function codes. The EPL receives the radio frequency messages, stores the function codes and corresponding instructions in a memory within the EPL, receives the infra-red signals from the portable terminal, determines the instructions associated with the function codes received from the portable terminal, and executes the determined instructions.
